Sealed Transmission

 admin



  • Methinks you are not as wise as you imply or have not thought out why the transmission is sealed. A 'lifetime' fluid is contained within a sealed environment and is not at all susceptible to the pollution or dirt as the old systems thereby lasting indefinitely, unless internal failure occurs.
  • Sealed Transmission Bearings Double sealed transmission ball bearings are available for use in both three speed car and four speed truck transmissions. There have been a lot of discussions about sealed bearings for this application and many people are apprehensive or skeptical, but I believe sealed ball bearings are the best choice.

The most common leak points on automatic transmissions are the input and output shaft seals. There is a shaft on the front of the transmission that slides either into the clutch plate or the torque converter that has splines on it. This shaft transfers power from the engine to the gears in the transmission and will have an oil seal around it.

  • i have a 2013 Chevrolet equinox it has 79433 miles on it has no dip stick for the tranny fluid someone told me that they are sealed
    saw some videos about how to change it has drain and fill plugs i found but would i need a pump and a fill plug and level surface
    but dealer said doesn’t need to be changed is this true i thought they had to be changed every 35000 miles any feed back on this would be helpful?

  • The owner’s manual will provide the recommended change interval of the ATF fluid. It will be necessary to determine if you use the vehicle for ‘normal’ or ‘severe’ service which have different intervals.

    In my humble opinion; if you tow a trailer on a regular basis this is a severe service interval vehicle.

    Unfortunately “sealed ” transmissions are not commonly serviced by the DIY.
    There are procedures and special equipment required to perform that service at the dealerships.
    Unlike the “common” style transmission where you remove the drain plug or drop the pan and replace the fluid removed.
    With these new style “sealed ” systems, some require the transmission fluid t be within a specific narrow temperature range and use a specialized drain / pump unit to drain and fill the transmission.
    It is not as easy as just removing X amount of quarts and add the same amount.
    Another item to consider, you may well void your warranty if you choose to attempt this on your own.

    Granted this isn’t your specific vehicle.
    But it will give you some idea what you may get yourself into.

    JMHO…
    It is a win for the MFGs and dealerships.
    But for the shade tree mechanic your just S.O.L.
    Plus, add to the fact you get a savvy shopper who knows the transmission is sealed and can only be serviced by the dealership.
    I’m sure they will want to see proof of service.

    My Camaro is also 97500 for normal service and 45000 for severe. I have been toying with the idea of dropping the pan to change the eight (8) quarts and filter. I am fortunate that the fill hole is on the passenger side top of the transmission. If I measure the amount collected when dropping the pan to put the same amount back in using a pump and hose to fill the ATF; the same technique used in the rear differential gear lube replacement.

    The only issue I see is having a collection container large enough to capture the entire area under the ATF pan, but i think a large aluminum roasting pan might be large enough for collecting.

    If careful I think an experienced DIY would be able to do the filter and ATF change.

    It is your vehicle and your free to do what you please.
    You need just be aware that if for some reason you get it wrong and you have a failure …
    I doubt the warranty will cover it and your pretty much on your own.

    There is a fill hole on the top of your trans. We reccomended servicing them at 30k and had many that the fluid was dark black already. If you need help through it let me know.

Some customers may comment on a red fluid leak from the transmission or transfer case area. Technicians may find that the fluid is leaking from the transfer case/PTU weep hole farthest from the transmission, near the passenger side.

Sealed Transmission System

This TSB applies to the following vehicles:

2008-2010 Buick Enclave

2008-2009 Chevy Equinox Sport

2009-2010 Chevy Traverse

2010 Chevy Equinox

2007-2010 GMC Acadia

2010 GMC Terrain

2008-2009 Pontiac Torrent GXP

2007-2009 Suzuki XL-7

2007-2010 Saturn Outlook

2008-2009 Saturn Vue

(with 6T45/70/75 AWD/PTU automatic transmission (RPO MHC/MH4/MH6) for GM or AF33-5 AWD/PTU automatic transmission (RPO M45) for 2007-2008 Suzuki and Getrag 760/790 transfer case)

The front wheel drive intermediate (inner) shaft seal may be leaking. Due to low ambient temperatures with various runout conditions between the intermediate drive shaft and the input shaft, the seal material may not properly seal automatic transmission fluid.

Replace the front wheel drive intermediate (inner) shaft seal with a new-design seal.

NOTE: Selecting the correct replacement seal is critical due to a 2008 mid-model design update. Use the following information to determine which seal to use.

For Acadia, Enclave, Outlook and Traverse:

Transmission

- For vehicles built prior to VIN Breakpoint 8J217964, use first-design seal P/N 19180998 (green).

- For vehicles built on or after VIN Breakpoint 8J217964, use the second-design seal, P/N 19206322 (green).

For Equinox, Terrain, Torrent and Vue:

- For vehicles built prior to VIN Breakpoint 86075818, use the first-design seal P/N 19180998 (green).

What Is A Sealed Transmission

- For vehicles built on or after VIN Breakpoint 86075818, use the second-design seal, P/N 19206322 (green).

For Suzuki XL-7:

- For vehicles built prior to VIN Breakpoint 86115983, use the first-design seal P/N 19180998 (green).

- For vehicles built on or after VIN Breakpoint 86115983, use the second-design seal P/N 19206322 (green).

NOTE: Second-design seals are not compatible with first-design transfer cases. Installing a second-design seal in a first-design transfer case will create a transmission fluid leak due to interference with the input shaft.

Sealed Transmission

Installing the replacement seal to the proper depth is critical. Use the DT-48078 Inner Drive Shaft Seal Installer with a J8092 Driver Handle to install the seal 2.8mm (0.11 in.) from the end of the input shaft.
